To send out all four from the start here on Tuesday would represent a gamble because a trip to Moscow is no walk in the park. But Klopp has never been afraid to go gung-ho and he knows ­he needs a result against Spartak after being held by Sevilla two weeks ago.

Klopp said: “Now I am excited, because we have all of the boys here. They all have to fit together and that is what we have to try.

“It is not about being spectacular, it is about being clinical and having perfect timing. We cannot just bring in all the artists — but if it fits together, we will do it.

“It is good to have them all, but that doesn’t mean anything. I don’t believe in names. I believe in performances.

“The balance has to be right. We are an offensive team but this is the Champions League. We need results. In the right moments, you need to do the right things.”

That defeat of Bayern is still fresh in the memory of Liverpool's German boss.

“The Bayern game was eight weeks ago,” he said. “They were the better side until we scored and then the game changed. That is how it sometimes happens.”

Liverpool have been through a lot since those pre-season days, notably the Coutinho-Barcelona saga and Senegal star Mane’s controversial red card at Manchester City.

But Saturday’s victory at Leicester ended a four-match winless run and gave confidence a shot in the arm before this showdown in Moscow.

Mane has been sorely missed while serving a three-match ban but Klopp has no worries about his freshness for Moscow.

The German said: “There is no issue about him starting. He trained completely normally. He has to get into the rhythm again and that is the challenge but he has looked good in training. It won’t be a problem for him to start.”

Klopp has a rich European pedigree from his time in charge at Borussia Dortmund, but has never been involved in a match in Moscow before and excitedly talked up the challenge.

“The atmosphere in Moscow is different, but the pitch is the same grass and pretty much the same size as Anfield,” he said.

“It’s an away game against a strong side, who were champions last year. It is exciting. It is my first time in Moscow, so it will be interesting.

“We know their style of play. They are a football-playing side and an experienced side. Last year, a new manager took over and immediately won the league. They’ve had a few injuries and struggled results-wise this season, but this is a different competition and they still have quality.

“We started with a home game and we didn’t win [the 2-2 draw with Sevilla] so that’s not positive, but in the end it is still a point. Obviously if we don’t win any away games then it will be difficult to get to the next round.”
